Sorry, but the colon cleansing thing is hippy bullshit. Essentially those cleansing kits are made up of ground psyllium husks (which can be purchased in bulk quite cheaply at any health food store, or online), mixed up with other miscellaneous ****--no pun intended. Ground psyllium husks, when mixed with water solidify quite nicely into a some nasty gel stuff, that takes the shape of whatever object the husks+water are in when the gel sets. You can try it for yourself with some water and bulk psyllium husks, or you can use metamucil, which is flavored and branded psyllium husks.

So, Anna, the nasty thing you've pictured is essentially a super disgusting, ****-infused jello mold, made in your colon. The asswipes who sell those colon cleansing kits add clay or herbs to their psyllium, which can make your poo jello salad turn fucked up colors. It did make for an amusing picture, however.

Glad you like it, now move on to Newbietown to introduce yourself, please!

Your best bet is through your doctor (or if you have other contacts) to get in contact with a biologist, a parasitologist especially, to see if it did happen to be anything.

I have to admit, it does look very unusual, to be all consistant like that. I know there are some long turds, but generally not that colour and they tend to be more loopy. I mean, unless you've been swallowing loooooooooooooooooooong pieces of asparagus without cutting them up.
